Enhanced sequencing and merging operations

Transcription

1 Enhanced sequencing and merging operations Objective: to redistribute tasks related to sequencing (e.g. in-trail) and merging of traffic between controllers and flight crews. Benefits: Controller availability by reorganisation and streamlining of tasks More regular spacing based on actual separation minima and thus an increase in capacity Increased flight crew awareness of traffic and anticipation of ATC instructions Implementation considerations New instructions will require specific functions on board aircraft related to HMI and automation Only pair-wise equipage required but maximum benefits from all equipped

3 Enhanced sequencing and merging operations heading then merge Pilot Controller Designates target XYZ456, select target 1234 Gives initial heading, waypoint and desired spacing XYZ456, heading 270 then behind target merge INKAK 8 miles behind Navigation Target direct INKAK (no turning point) Ownship on heading then direct INKAK (not on target trail) Air-air surveillance Target position and speed (no intent required) Identifies target XYZ456, target 1234 identified, 8 o clock, 30 miles Resumes when spacing obtained then, adjusts speed to maintain spacing INKAK 8Nm 1234 XYZ456

7 In-trail procedure in oceanic airspace Objective: to allow in-trail ADS-B equipped aircraft in non-radar oceanic airspace, which may not be longitudinally separated from each other, to climb or descend through each other s flight levels. Benefits: Improved utilisation of the North Atlantic oceanic airspace by facilitating a higher rate of flight level changes yielding better flight efficiency (e.g. fuel savings, avoiding turbulent flight levels) Implementation considerations Safety studies needed to determine spacing value

9 Enhanced crossing and passing operations Objective: to provide controller with new set of instructions to solve conflicts e.g. directing flight crews to cross or pass designated traffic aircraft while maintaining a given spacing value. Benefits: Increased controller availability through reorganisation and streamlining of tasks Increased flight crew awareness of traffic and anticipation of ATC instructions Implementation considerations New instructions will require specific functions on board aircraft related to HMI and automation Only pair-wise equipage required but maximum benefits from all equipped
